The only "problem" I see you have is that the stock has either been replaced maybe or sanded heavily. It doesn't have the matching serial number and the proofs that it should. The metal looks nice on it. Hardwood stock it is. You may have paid a little more than what a sanded stock rifle should have brought, but if you really wanted one, why not? This one is a little more special though in that it is a (W) stamped one. If memory serves, this means it was a test rifle for Walther. (W)=Walther. An early one like this may explain the hardwood stock instead of a laminated stock. Other than the stock, rifle seems nice.
Oh yea, it's also a "push button" type too! Bolt release type rather. Nice! These are rare'er too.
